Tweeing Problems

I’m having this issue with the Motion Tween.

I have a Glow set around a button and have that Motion Tweening, so that the Glow increases when the mouse is rolled over a part of an image. Then, when I add text when the Glow is at its maximum, the Motion Tween switches over to the text, thereby causing the part of the image to move toward the text instead.

I’ve done this tween like 9 times before in the same document, and it’s worked all of those times. Why is this any different?

Please help!
